How to Measure for Flooring

Work out how many square metres of flooring you need, including wastage.

Updated

Flooring is sold by area, so you need to know the size of each room in square metres (m²).

Step 1: Sketch the floor plan

Draw a rough plan of the rooms you want to cover, including hallways, wardrobes and doorways.

Step 2: Measure each area

Measure the length and width of each rectangular area at its longest points, in metres. Multiply length by width to get the area. For L-shaped rooms, split them into rectangles and add the areas together.

Step 3: Add wastage

Add around 5–10% to allow for cuts and offcuts. Rooms with lots of corners, or planks laid on a diagonal, usually need closer to 10% or more.

Example

A living room 5.0 m × 4.2 m = 21 m². Adding 10% wastage gives about 23.1 m².
